Wondering if there's a util that will help me select the screen refresh rate when playing a DirectX game.
My windows refresh rate is 85Hz in Windows, but seems to get set to 60Hz when in a DirectX game which is not good for me.

I'm not aware that you can adjust the refresh rate for DirectX. You ususally have controls within the setup of the graphics cards where you can define the refresh rate under differing circumstances.
Have a look in display properties and see if there is anything under OpenGL settings etc..

I've found that DirectX takes the display properties from your windows settings, eg;
for 10x7x32 and 8x6x32I use 85hz refresh (I don't use other res's). If I use the same settings in a game (10x7 32 bit colour) it'll use the 85hz. selecting 16bit colour in a game takes the refresh rate back to a horrid 60 or 75hz
I hope that make sense.

XRS is right, you normally have a refresh rate for each res in the control panel for your video card. The windows one is basically setting the maximum that will try to be displayed.
If you are getting 60fps in games thats more than playable. You may want to see if you have an option to disable Vsync. This means that the graphics card will wait for the monitor to be ready to refresh the screen, and can slow it down.

I don't find 60Hz good enough - besides that refresh is bad for your eyes and I'm pretty close to the screen.
So to answer my question, there's no way to set the default refresh rate (Hz) for a DirectX game at a particular resolution ?
(Normal windows mode lets me select 120Hz for 800x600x16)

DazV,
do what I said and disable the Vsync.
What card are you using?
It may not have enough processing power to give you what you are asking for, so you may need to get a better one. You need to look atthe refresh rates in your drivers tho, as it will never go above this.

Easily sorted.
When in Windows go through all the possible modes, that is all resolution/colours combinations.
For each one set the refresh rate at the max it will work with.
The game will change the resolution and the number of colours without you knowing it sometimes and it will always use the refresh rate windows has remembered for that particular setting, even if it is one you would never normally use when in Windows and it isn't the one you are currently using.
Most likely it is going to 800x600 with 256 colours or something like that and you haven't set the refresh rate high enough when windows is set to that.

Cheers mate, I'll give it a whirl.
...Gave it a whirl, set windows to 800x600x16@85Hz, 800x600x8@85Hz, 800x600x32@85Hz and it STILL sets itself to 60Hz for 800x600.

Sounds like you have the adaptor refresh rate set to Optimal or Default in the Nvidia Geforce tab in display, have a play with these settings. You'll have to change screen sizes and change their refresh rates as well. DONT SET HIGHER THAN THE MONITOR CAN COPE WITH (only possible if you've not got the correct monitor selected)

Dominic,
Monitor is an IIYAMA Vision Master Pro, which can easily handle those modes.
I don't have the refresh set to optimal, I have it specifically set to 85Hz. Would that make a difference ?

BT52, do you use an IIYAMA driver or just the standard monitor driver.
I think that's where I'm going wrong - I'll head off to the IIYAMA site to get their driver.

Oh you HAVE to have the right monitor specified in windows or the refresh rates will go horribly wrong.
Got a 17" Pro at home, but at the moment looking at a lovely 19" Pro450. Absolutely great monitors.
